Clamp Type Shaft collars are designed to make fitting or adjustments quick and easy to help reduce downtime. With just the need of a hexagon drive, quick installation and adjustments can be done to Clamp Type Shaft Collars. Clamp Type Shaft Collars are used in many applications where access is restricted they are very useful where frequent changes are required or setup adjustments needed.

Our Clamp-style shaft collars designs solve the problems associated with the set-screw collar. We have one-piece and two-piece designs. The screws are used to compress the collar and lock it into place and keep the screws from protruding into the shaft. They have a design that makes it easier to maintain and helps to avoid any shaft damage by compressing the collar its self. The force from the tightening is distributed uniformly around the shaft, giving an increase of nearly twice the holding power of set-screw collars.

Keyed shaft collar

These collars have an added element of a key slot. This could be used to help in applications where the load is increased and stability is needing to be increased so the collar doesn't slip.
